Filament that suits well

Bought this plastic to test our ideas, and was literally surprised, it not only does what it should, it also has a damn good quality for it's price. Thank you guys. Btw what I would like to have - a bit more videos and guides on your production

Conductive filament

Appears to have arrived in good condition. Ohmmeter confirms it's conductive (resistive). Haven't used it yet; it's for an upcoming project.

Excellent Material and Excellent support from Protopasta.

I was initially having issues printing this material. I contacted Protopasta and they worked with me to troubleshoot and identify the issues I was having. Spoiler alert, the issue was with my machine, not the filament. Now that the bugs have been ironed out, I am up and running. I can't recommend protopasta and this material enough.

My favorite

This had been my favorite filament of any that I have tried. It has produced amazing quality results for me. I don't even use it for the conductive properties, I use it because it prints so smoothly.

I have had a really excellent experience with this material. I was able to print a nearly perfect Benchy on my first attempt using the print and material settings from Proto-Pasta. The only issues I’ve run are into that the filament is brittle and can break if there is any resistance in your feed, and it can take a quite a bit of regular pla to clear residue from the hot end.
